Desktop Kobo MacOS app

Hi

Since years I used the Kobo Destop app on MacOS to sync my Kobo reader to Calibre in order to convert my books I bought on Rakuten from ePub to PDF.
Since few days I got a message from Apple warning me that this app won't work anymore soon as it won't be compatible with the new MacOS system (stop Roseta support app).
I know now that the Rakuten Kobo desktop app is not anymore supported here in Europe by Rakuten (since 2024 it seems) then no chance to get an update.
From then I want to know if it will be possible to continue to use Calibre to do the conversion of my purchased book knowing that the solution on Rakuten's side is to use the web app so no more physical connection between my Kobo reader and Calibre (and then how to use the oBok DeDRM I use today?) ?

Thanks for your advice
BR

You can install the ACSM Input plugin and download the ACSM file which will become ePub. And then when you are properly configured with DeDRM, you'll be able to remove the DRM from the ePub. Then you can convert the ePub to PDF.

Hi

Finaly find the solution
Sync my Kobo eReader once purchased a book
Once the book on my Kobo connect it to my Mac as usual with a cable and then in Calibre once the Kobo eReader is recognized in the DeDRM plugin the book is there ready to be converted in PDF as usual.
I can now remove the Kobo app from my Mac without any trouble

Or you just go to Kobo and sign in, then access your books on the web. Look for the 3 dots and select download. If there's DRM, you'll get an ASCM file, if not, then you'll get an epub with a long file name (usually including the ISBN). If you install the DeASCM plugin, you just import the ASCM files directly into Calibre. The epubs will import straight away.

By syncing on your Kobo, you run the risk of LCP DRM files.

That is not a problem.
